9bbfb849b1 util.format: Restore "freeze" serialization behavior in logging 
This was implied with the "debug" preset and does nice things like turn
util.set objects into "set{a,b,c}" instead of the quite verbose thing
you get otherwise.

328447c2b1 util.format: Tweak serialization of %q formatted entries 
Improves serialization of function references especially, the built-in
default handling of that in util.serialization is not the most
informative.  Now, along with the function metatable from util.startup,
the actual function can be found by filename and line number.

f8e73eba98 compat: Use table.pack (there since Lua 5.2) over our util.table 
Added in d278a770eddc avoid having to deal with its absence in Lua 5.1.
No longer needed when Lua 5.1 support is dropped.

c551d3d8dd util.format: Skip control code escaping when doing full serialization 
Fixes that a multi-line string ended up "like\
\9this" instead of "like\nthis" as can be demonstrated by somehow
initiating a connection to a HTTP server.

0e997ab3f9 util.format: Optimize most common integer format 
A search for log formats in use points to %s being the most common,
followed by %d, so worth having a fast path for that. %g works well with
most numbers and is what Lua 5.1 and 5.2 used

1eca4e8870 util.format: Ensure sanitation of strings passed to wrong format 
Ie. log("debug", "%d", "\1\2\3") should not result in garbage.

Also optimizing for the common case of ASCII string passed to %s and
early returns everywhere.

Returning nil from a gsub callback keeps the original substring.

d4c1451794 util.format: Escape invalid UTF-8 by passing trough serialization 
Should prevent invalid UTF-8 from making it into the logs, which can
cause trouble with terminals or log viewers or other tools, such as when
grep determines that log files are binary.

7e09f662cb util.format: Allow newlines but ensure following lines are indented

lines and b) not mangle tracebacks.

f179b18e2b util.format: Fix missing backslash in pattern 
Made the pattern match a longer range than intended, but with no effect
since those characters are not present in the 'control_symbols' table.

3f1d93bb4e util.format: Escape ASCII control characters in output 
This should offer some protection against doing evil things to
terminals. Doesn't protect against pure broken UTF-8 garbage however.

See #734
